Good Chromaggus-kill by Immortality (EU-Onyxia).
One of my first movies i really tried to make them look good with my poor WMM-skills xD But i'm still a beginner at this stuff (and sorry for my bad english :/).

Breath's: Ignite Flesh/Corrosive Acid
I tried to choose some kinda music that fits this boss, so here we go:
Lordi - Would you love a monsterman
Blind Guardian: Time stands still (on the iron hill)
Lordi - Pet the destroyer (yeah, i know... i'm pretty much addicted to them, after they won the Grand Prix :D)
Blind Guardian - Barbara Ann

If you got any tips for me, you may speak freely :)
Wanna make some further movies from AQ40 anyways...

But now enough talk: have fun watching :).
